The more you berate yourself the more you stop yourself from experiencing joy at whatever you achieve. Remember my child getting 100% is not the only sign of success. What is success to you? Never being wrong? Being right always, is not being successful. But being wrong and knowing why you are wrong and accepting that there can be improvement next time, that is true success. So stop being harsh. You so often ask God to forgive you. It may surprise you my child that you don’t ever have to ask for it. God neither forgives nor does He not forgive. You have to forgive yourself and true forgiveness means accepting and understanding your mistakes, taking responsibility for them, not feeling any sense of guilt, and being joyous at being given yet another opportunity to improve yourself. That my dear child is forgiveness, whether it be yourself or others.
